Leaked documents have shed new light on the China’s government’s network of prison camps in the far western region of Xinjiang, where as many as 1 million Uyghur Muslims have been detained without trial. The Chinese government says these prisons offer voluntary education. But the leaked documents reveal a campaign to force prisoners to change their language, culture and religious beliefs. British human rights lawyer Ben Emmerson said, “It is very difficult to view that as anything other than a mass brainwashing scheme designed and directed at an entire ethnic community.” The Chinese government has denied carrying out any human rights violations against the Uyghurs.
